APPARATUS FOR MANUFACTURING WATER-GAS.

SPECIFICATION forming part of Letters Patent No. 532,778, dated January22, 1895.

Application filed December 6, 1892. Serial No. 454,222. (No model.)

' To all whom t may concern:

Be it known that I, ARTHUR GRAHAM GLAS- GOW, a citizen of the UnitedStates, residing at the city and county of Philadelphia, State ofPennsylvania, have invented a certain-new and useful Improvement inApparatus for Manufacturing Water-Gas, of which the following is a trueand exact description, reference being had to the accompanying drawing,which forms apart of this specification.

My invention relates to apparatus for manufacturing water gas, and hasforits object to provide a supply of steam for the generator or vgenerators for the blower engine or engines and for the other usualpurposes with a minimum expenditure ofpfuel. It has been attemptedheretofore to utilize the heat of the waste gases issuing from thegenerator or superheater-according to the type of the apparatus-to heata boiler from which the steam supply of the generator is drawn, but asthis source of heat is irregular and uncontrollable, there being norelation between the supply and the demand, this attempt has met withindifferent success in the manufacture of straight water gas, and has, Ibelieve, been entirely abandoned in the case of carbureted water gas.

Generally speaking, my invention consists in combining with thegenerator a boiler, the tubes of which form part of the conduit forescaping gases, and also aboiler heated by means independent of theescaping gases, uniting the steam spaces of the boilers, and alsopreferably the water spaces as hereinafter described.

My invention will be best understood as described in connection with thedrawing in which it is illustrated, and which shows a water gas plant inelevation and partlyin sec tion.

A, is the water gas generator, a indicating the air blast and M, thesteam lsupply pipe.

B, is a fixing chamber, shown as superimposed on the generator.

O, is the flue leading from chamber B, connecting with the gas Hue D,and delivering when valve E is open, into the blast gases conduit G, G.

S, is the inlet for the air necessary to complete the combustion of theescaping blast gases provided the iiue G, be practically closed asshown.

In case the space G, be left freely open to the atmosphere, the indraftof air to complete the combustionof the escaping blast gases isregulated by the damper P; E, indicating the valve by which the courseof the gases is governed.

F, is a boiler set in the blast gases conduit G, G; the upper and lowerparts of which connect through the boiler flues, f, f, dac.

II, is the feed water supply pipe; I, a steam pipe leading from thesteam space of boiler F; J, a Water pipe leading from thewater level ofboiler F, toa boiler K,- with the steam space of which boiler, pipe,.I,connects as shown. This boiler K, is independently heated as by afurnace L, and preferably from it leads the steam supply pipe M.Obviously the steam pressure in the two boilers F and K, is always thesame as they are connected by pipe I, and the boiler heated by meansindependent of the gases escaping fromthegas generator can be so run asto obtain the full benefit of all the waste heat of the gases passingthrough boiler F, While at the same time its own independent furnacewill, and does insure a sulficient heat supply at all times to maintainthe necessary generation ofrsteam for use in the generator orgenerators, blower engines and for the other usual purposes.

While Ihave claimed the boiler Fas situated in the conduit for gasesleading from a superheater may be inserted between the gen- Y erator andboiler as shown in the drawing at B and the gases first passed throughthis. It is also of course obvious that not only the blast gases butalso the commercial gases may be'passed through the boiler situated inthe gas conduit in a manner well known in the artas shown in the UnitedStates Patent to J. L. Stewart, No. 333,691, of January 5, 1886, and Ido not wish to be considered as limiting myself \to theexactconstruction shown.

While in the foregoing description I have in general indicated theboiler heated by the escapingblast gases as of tubular design, theinvention is equally applicable to any form of steam generator. Havingnow described my invention, what ICO I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a Water gas generator, of a boiler having firetubes or ues, constituting part of the conduit for the gases escapingfrom the generator whereby the boiler will be heated by the hot gaseswhich intermittently escape from the generator, a boiler heated by meansadapted to act constantly thereon and independent of the intermittentand Varying volume and heat of the gases drawn olf from the generator, acon-` nection between the steam spaces of the two boilers and a pipe forconveying steam therefrom whereby the benefit of the heat of the gasespassing oft from the generator will be obtained, and at the same time aconstant supply of steam will be insured bythe boiler heated by theconstantly acting source of heat.

2. The combination with a watergas generator, of a boiler having fire`tubes or hues constituting part of the conduit for the gases escapingfrom the generator whereby the boiler will be heated by the hot gaseswhich intermittently escape from the generator, a

boiler heated by means adapted to act con-` stantly thereon andindependent of the intermittent and varying volume and heat of the gasesdrawn ott from the generator, a connection between the steam spaces ofthe two boilers, a pipe for conveying steam therefrom and an air inletleading into the gas conduit lsaine time by the boiler heatedby `stantlyacting source of heat.

below the boiler therein to permit the entrance of air to complete thecombustion of the gases, all substantially as specified and so that theheat of the gases passing off intermittently from the generator may beutilized and at the same time a constant supply of` steam insured bytheboiler heated by the constantly acting source of heat.

3. The combination with a water gas generator of a boiler having lliretubes or flues constituting part of the conduit for the gases escapingfrom the generator, a feed conduit leading to said boiler, a boilerheated by means adapted to act constantly thereon and independent of theintermittent and varying volume and heat of thegases drawn oft from thegenerator, a water connection leading from the water level ofthe flueboiler to the boiler heated by the constantlyactin g source of heat,

a connection between the steam-spaces of the ltwo boilers and apipe forconveying `steam therefrom, all substantially as specified and `so thatthe heat of the gases passing oli intermittently `from the generator maybe utilized and a constant supply of steam insured at the the con-ARTHUR GRAHAM GLASGOlV.
